Rolls-Royce has completed successful altitude and operability tests for the F130 engine, intended for the B-52J bombers of the United States Air Force. Tests were conducted at the Arnold Engineering Development Complex in Tennessee, validating the engine's performance under simulated altitude and challenging operational conditions.

The F130, based on a proven commercial platform, is designed to enhance fuel efficiency and reliability while replacing aging B-52 engines. The modernization plan for the B-52 includes advanced radar, electronic systems, and structural improvements, ensuring operational capability into the mid-21st century. The collaboration between Rolls-Royce engineers and Air Force personnel reflects strong cooperation between the aerospace industry and U.S. military institutions, advancing towards integration and certification of the engine.
